Good Morning All, Has anyone ever replaced the couch, (Jackknife) I think they call them in the TT? The one in the used TT we bought is in pretty good condition, but, was just wondering if and when it needs to be replaced, where do you find them to fit and are they hard to put in? Also, when we got the TT and I was cleaning under the couch, there was an inflatable mattress under it. I guessed it to be for the couch, but, HOW do you blow them up?:hihi: Feel crazy asking some of these simple questions, but, how else do you learn the simple ways? Thanks Everyone
